Abstract
Official abstract text for this publication.
Disclosed is a porous membrane comprising a cellulosic material and a copolymer of the formula: A-B-A (I) or A-B (II), wherein block A, for example, polyglycerol, a polymer of allyl glycidyl ether, or a copolymer of glycidol and allyl glycidyl ether, or a polymer of allyl glycidyl ether or a copolymer of glycidol and allyl glycidyl ether wherein one or more allyl groups having been replaced by hydrophilic groups. Also disclosed is a method for preparing such a membrane.
First claim
Opening claim text (preview).
The invention claimed is: 1. A porous membrane comprising a cellulosic material and a block copolymer of the formula: A-B-A (I) or A-B (II), wherein block A is: (v) a copolymer of glycidol and allyl glycidyl ether, wherein one or more of the allyl groups of the copolymer have been replaced with a group of the formula: —(CH 2 ) a —S—(CH 2 ) b —X, wherein a is 3 and b is 1 to 3, and X is selected from an acidic group, a basic group, a cation, an anion, a zwitterion, halo, hydroxyl…
